I'm 16 1/2 post injury and six months after my accident my urologist strongly suggests that that I get supra and has been rock solid for the most part every since then! The only reasons that I might have got a UTI is not drinking enough water or due to other illness. One thing I have not heard discussed before is getting your catheter flushed out on a regular basis now to my old school urologist he strongly recommend that this using an acid-base solution retained in the bladder for about 10 minutes. Also nobody has mentioned any proud flesh around the catheter site is very common with this type of catheter and use silver nitrate to reduce it.I am 3/4 complete level injury and have been doing this 16 years can't be going wrong. Besides my current urologists is a cancer research type of individual and likes to take a scope about everyone a half years to make sure everything is checking out on the good side. Yes state insurance money covers all this, having individuals using alcohol wipes when changing over from one bank to another is another way to reduce infections
